Ok, you guys are going to freak and probably kick me off CB, but my kids have pet rats. I thought Puma was insane when he first came up with this idea, but I swear they are the greatest pets! ODD (theater DD these days, I suppose?) wanted a hamster and Puma is the master of research, and he read that hamsters are mean and bite and smell, and rats are better! So far so good! Puma Jr has literally put Mr. Bundles through bar routines on her American Girl Doll gymnastics set, and he doesn't seem phased at all! (Yes, I do tell her to stop lol)I wouldn't even blame him for biting her, but he never has.
